Milky Plasma, Murky Diagnosis: Urgent Plasma Exchange for Severe Hypertriglyceridemia-Induced Hyperviscosity Without Pancreatitis, but With Myocardial Infarction.

ABSTRACT: Severe hypertriglyceridemia can increase the risk of acute pancreatitis, but also clinically significant hyperviscosity syndrome characterized by the typical signs of neurologic and visual manifestations. Hyperviscosity syndrome is a well-established medical emergency. However, hyperviscosity syndrome induced by hypertriglyceridemia may be under-recognized, particularly when pancreatitis and other classical signs of hyperviscosity syndrome are absent. We describe an index case of extreme hypertriglyceridemia presenting with cardiorespiratory symptoms (chest pain and dyspnea) due to suspected hyperviscosity, but without clinical or radiographic evidence of pancreatitis, successfully treated with therapeutic plasma exchange (TPE). We then review the limited, but growing body of published cas
